The U.S. Supreme Court heard arguments today in the latest challenge to the Affordable Care Act that could upend a key provision.

At issue, the constitutionality of a task force that recommends what preventive care treatments should be covered by private insurance with no cost to patients.

prep, pre-exposure prophylaxics medicine, which are medicines that can help prevent the spread

of HIV and are highly

effective at doing so. They have religious objections because they say that these medicines

encourage same-sex relationships and intravenous drug use. So they went to federal court,

challenging the requirements, arguing among other things, that the structure of this task force

to be nominated by the president and confirmed by the Senate.

the task force. So I want to underline that point here. The Trump administration is now defending

part of the Affordable Care Act, also known as Obamacare, after working to undo it for years. What is their argument?
